Tower Testing Capabilities Country’s largest tower testing facility L&T has installed a state-of-the-art tower testing station at Kancheepuram, near Chennai. Acclaimed as one of the best in the world, this is the country’s largest tower testing station. This is equipped with facilities to carry out tests on square or rectangular base lattice tower, monopole, tubular structure and guyed tower for capacities up to 1200 kV. This testing bed apart from analyzing the accuracy of the assumptions made in the design calculation, ensures that the tower members meet the optimum levels and desired performance criteria. This facility is incorporated with the specially designed data acquisition and control system and latest equipment to support the operation. The laboratory is equipped with digital UTM and a crane. Due to its dimensions (85 m height; 70 m boom length), the crane spans across the entire area of testing and erection operations. The station also has a proto fabrication unit to carry out modifications in any part of the tower during the course of testing. Operations of winches (65 Nos. each 5 t) are controlled by a state-of-the-art SCADA program coupled with auto, semi-auto and manual options.

Manufacturing capabilities

State-of-the-art tower factories L&T has 1,00,000 mtpa tower manufacturing facilities strategically located at Puducherry and Pithampur. Both plants are equipped with the latest CNC line for fabrication of towers and microprocessor based temperature controlled eco-friendly systems for galvanization of tower members. Fabrication Process: Multipurpose CNC machines directly read the drawings, punch, stamp and cut steel. Heavy duty machines perform even the heaviest of bends without distortion. Strategically positioned EOT cranes efficiently perform material handling. Galvanizing Process: The furnace is controlled by microprocessors to give control on the bath temperature. The drying oven uniformly dries and pre-heats the steel, which removes spurting and gives an excellent surface finish to the product. L&T’s factory has got one of the biggest (size 10 x 1.2 x 2 m) galvanising bath available with tower manufacturing companies and uses the environment friendly methods. Rolling Mill: To ensure timely availability of quality raw material, a rolling mill of 40,000 mtpa capacity was set up at Puducherry factory to produce angles, channels and re-bars
